The invention relates to a process for refining a biomass having a dry matter content of 5 -95wt.%， based on the total weight of the biomass， wherein the process comprises the subsequent stages of (a) water extraction under atmospheric pressure conditions and at a pH of 5 to 7， (b) prehydrolysis with water， steam or a mixture thereof at a temperature of 100°C to 200°C， and (c) hydrolysis at a pH of less than 7. In a further aspect of the invention， one or more valuable by-products such as for example vegetable oil， hemicellulose， lignin， furans， organic acids and monomeric and/or polymeric sugars are recovered from the refining process. The present invention also relates to a dissolving pulp obtained by the process according to the invention， and to the use of the dissolving pulp for the production of cellulose acetate.
